Who could believe that it's been three beautiful years since we were blessed with the wondrous and imaginative movie Sharknado?!

That's right, Sharknado celebrates its third anniversary today, and I think you'll agree we're a lot better off for its existence. After all, without Sharknado we wouldn't have so many other things, including but not limited to, Sharknado 2: The Second One, Sharknado 3: Oh Hell No!, Tara Reid's career renaissance andthe upcoming Sharknado: The 4th Awakens.

So in order to properly celebrate this most hallowed of days, take a look below at the carefully selected Sharknado trivia and rejoice in its third anniversary:

1. The film was shot surprisingly quickly

You'd be forgiven for thinking months and months of filming went into Sharknado, but in fact the director managed to shoot the whole film in just 18 days.

4. An actor who passed up the lead role totally regrets doing so

Before Ian Ziering took on the role of Fin Shepard, Steve Guttenberg was offered the lead role and turned it down! However, after seeing the film's cult status, Guttenberg was so overcome with regret that he took up a role in another Syfy film, Lavalantula (a movie is about fire-breathing tarantulas which attack Los Angeles). However Guttenberg is set to appear in Sharknado 4: The 4th Awakens.

But Guttenberg wasn't the only one to have doubts about the film...

5. Ian Ziering almost didn't take the role

Ziering was only talked into doing the film because his wife was pregnant at the time, and he needed work to support his family, and also maintain his health insurance!
